1.-2. (09' or older) visual Axanthic(s) (depending on your stance on in/line breeding.
.1 Spider (08'-09')
.1 Pastel (08'-09')
.1 Pinstripe (08'-09)
.1 Mojo / Lesser (08'-09')
.1 Cinnamon/BlackPastel (08'-09')

That way you can try breeding the visual Axanthic x the Females in the upcoming 2010-2011 season, and maybe produce some CoDoms and be certain that they are 100%het Axanthic.
(As well as get some breeding experience.)

Hold back ALL of the females that you produce.
Sell the males, and put the money away.
(Repeat this again in the 2011-2012 season as well, but hold back a CoDom 100%het Ax. of each CoDom you are working with.)

After a season or two, when the females that you produced and held back are grown and the market has come down some, you can use that money to pick up a Double CoDom male that is also a visual Axanthic to breed them to.
(BumbleBee Ax, Pewter Ax, LemonBlast Ax, or FireFly Axanthic.)

Starting with just these Base Morphs, if everything goes well, you could be producing some of the following Combo's in as little as 3-5 years:

Pastel Axanthics
Spider Ax's
Pinstripe Ax's
Cinnamon Ax's
Pinstripe Ax's
Mojo / Lesser Ax's
SuperPastel Ax's
Bumble / KillerBee Ax's
Lemon / KillerBlast Ax's
Pewter Ax's
CinnaBee Ax's
FireFly Ax's
Spinner / SpinnerBlast Ax's
Pastave / LesserPastel Ax's
QueenBee Ax's
... and many, many more.

I'm not sure that you would ever run out of the potential for more Combo's with those Morphs, but if you did you can always pick up some other CoDom females.

If all that gets boring to you, just throw some other Simple Recessive Mutations into the mix.
Hypo/Ghost x Axanthic (True Ghost)
Albino/Lav. Albino (Snow)
And then there is always Clown, Pied, Genetic Stripe.....
